- the oldest known fungi.
-Their gametes still have flagella. There aren’t that many well known,
- one of the causes currently killing amphibians, known as amphibian decline.
- include the common black bread molds and fruit molds that often spoil your lunches.
- reproduce sexually when two nearby hyphae grow toward each other (lead by pheromones) until they touch. They then fuse together and form a a zygosporangium.
-This structure holds the genes from both parent cells until conditions are right (like moisture returns).
-When things are “lookin” good, the cells will fuse their nuclei (fertilization) to form a sporangium, which is a stem-like projection in which spores are made.
dark lump is where zygosporium and hyphae meet
-produce a saclike structure that produces spores (hence the common name) called an ascus hence the taxonomic name).
-Some yeasts turn glucose into ethanol and CO2, which we use in bread making (the ethanol is burned off, the CO2 causes the bread to rise)
- beer and wine making (the yeast turn the sugar from the hops or grapes into booze and the CO2 makes it bubbly).
acrospore- the spore at the end of the fruit-bearing part in fungi
-saprochic fungi that feed on wood
